The things of the earth ill beseem you.

By the righteousness of God! The world and its vanities, and its glory, and whatever delights it can offer, are all, in the sight of God, as worthless as, nay, even more contemptible than, dust and ashes. Would that the hearts of men could comprehend it! Cleanse yourselves thoroughly, O people of Bahá, from the defilement of the world, and of all that pertaineth unto it. God Himself beareth Me witness. The things of the earth ill beseem you. Cast them away unto such as may desire them, and fasten your eyes upon this most holy and effulgent Vision. That which beseemeth you is the love of God, and the love of Him Who is the Manifestation of His  Essence, and the observance of whatsoever He chooseth to prescribe unto you, did ye but know it.
